New: ESP32 Support

This release adds liblsl-ESP32, a clean-room C reimplementation of the LSL wire protocol for ESP32 microcontrollers with full secureLSL encryption support.

Highlights

• Protocol v1.10, wire-compatible with desktop liblsl and secureLSL
• ChaCha20-Poly1305 authenticated encryption with X25519 key exchange
• Sustains up to 1000 Hz with near-zero packet loss
• Zero measurable encryption overhead on push path (dual-core async architecture)
• ~4,000 lines of C, ~200KB SRAM footprint

Included

• Core ESP-IDF component (liblsl_esp32)
• 4 examples: basic_outlet, basic_inlet, secure_outlet, secure_inlet
• Benchmark suite with desktop Python collection scripts
• Documentation integrated into secureLSL mkdocs site

Hardware Verified

• ESP32-DevKitC v4 (WROOM-32) over 802.11n WiFi
• Bidirectional encrypted interop with desktop secureLSL
• 0% packet loss at 250/500 Hz, 0.02% at 1000 Hz
